It's very likely that Apple will make OS X Yosemite available for the public to install on their Macs for free after the event this week.

Apple's 16 October event: Retina iMac
It's possible that Apple will also use this week's special event to announce new Macs, something that the company has done in the past during this frame time. The most prominent new Mac rumour relates to Apple's all-in-one desktop computer: the iMac.
Rumour has it that Apple will launch a 27in 5K Retina iMac on Thursday, which is likely to be very costly but also pretty amazing, particularly for photographers and designers.
Apple's 16 October event: New Mac mini
It's quite likely that this is wishful thinking, but Apple's "It's been way too long," invitation tagline got us thinking: Is Apple finally going to update the Mac mini?
The Mac mini is long due an update - the last model came out in early 2013. There isn't much evidence to support the idea that this month is the month Apple is going to launch a new Mac mini though, so we'll simply have to wait and see.

Apple's 16 October event: New Apple TV
Another product that came to mind when we saw Apple's invitation tagline was the Apple TV, which also hasn't been updated since early 2013 and even that was only a minor update.
Set-top box and streaming services have grown in popularity so much since the last Apple TV was launched, and Apple has already confirmed that it doesn't consider the product to be a "hobby" like it once did, but whether we'll get a hardware update or simply more software updates is another question. We're keeping our fingers crossed for a hardware update though.
In fact, some have even suggested that Apple will go as far as unveiling a fully-fledged Apple TV set during the event, though we think the likelihood of that is quite slim. That said, Apple could surprise us. Anything's possible.
Apple's 16 October event: Anything else?
There has been some chatter about new iPods (we're not convinced) and new MacBooks (but they were already updated this year), as well as a new Mac Pro, which we think is the most likely out of the three but there's still not much evidence to support the theory.
You can also expect to see the rollout of Apple's continuity features, which will be a real boon for anyone using iOS 8 and Mac OS X Yosemite. iOS 8 will also get iCloud Photo Libraries in beta form.
